The Brute Force Approach

First create a new NetBeans project with the name "HelloQtOnNetBeans" and then perform the following steps:

• Create a new empty source file in the project by right-clicking on the 'Source Files' directory and selecting 'Empty C++ File'; give it the name 'HelloQtOnNetBeans.cc'. Copy the source from the section 'Listing of HelloQtOnNetBeans.cc' of the Appendix into the file and save it.
• Create a new empty header file in the project by right-clicking on the 'Header Files' directory and selecting 'Empty C++ File'; give it the name 'HelloQtOnNetBeans.h'. Copy the source from the section 'Listing of HelloQtOnNetBeans.h' of the Appendix into the file and save it.
• Create a new empty file in the project by right-clicking on the project name 'HelloQtOnNetBeans' and selecting 'Empty C++ File'; give it the name 'HelloQtOnNetBeans.pro'. Copy the source from the section 'Listing of HelloQtOnNetBeans.pro' of the Appendix into the file and save it.

In the project-properties view enter the name of the output-file under the link tab: './hello'.

Finally edit the 'Makefile' that you will find in the NetBeans project-section 'Important Files':

1. Remove 'build: .build-pre .build-impl .build-post' and replace it with

   build:
   	qmake -o Makefile-Qt HelloQtOnNetBeans.pro
   	make -f Makefile-Qt

   Don't forget to enter a 'Tab' at the beginning of the qmake- and make-line!


2. Remove 'clean: .clean-pre .clean-impl .clean-post' and replace it with

   clean:
   	make clean -f Makefile-Qt

   Again: don't forget to enter a 'Tab' at the beginning of the make-line!

The line 'qmake -o ..' will automatically create a 'make'-file named 'Makefile-Qt', which is compatible with the GNU C/C++ build-process in the NetBeans C/C++ pack. The process is based on the Qt-project file (here 'HelloQtOnNetBeans.pro') and on the NetBeans C/C++ project properties, you set before. The other lines define the 'make'- and the 'clean'-commands.

Now you can build the program by right-clicking on the project name 'HelloQtOnNetBeans' and selecting 'Build Project'. You can also clean your project or select 'Clean and Build Project' in order to start with a clean environment. Selecting 'Run Project' will start the program and you will see the following window on your screen:
